The illustrated embodiment of the present invention includes a frame 35having a bed plate 36 at the front end of the machine and twotransversely spaced parallel upstanding frame plates arranged above thebed plate 36, the right frame plate being represented by the numeral 31and the left frame plate by the numeral 38.

The paper tape T to be wound into individual consumer rolls is obtainedfrom a large supply roll 39 suitably mounted on the rear of the machineso as to rotate .about a horizontal axis. A suitable brake device (notshown) is preferably operatively associated with the tape supply roll 3Sso that a drag is placed on the tape T pulled from this roll. The tape Tis pulled toward the front of the machine through any suitabletensioning device 40, such device being shown las comprising a series 0fvertically staggered horizontal rods spaced longitudinally of themachine and mounted on the frame 35 and alternately over and under whichthe forwardly moving tape T passes.

After leaving the tensioning device 40 the tape T slides over asupporting base 4| provided on the frame. An adjustable electricallydriven skiver 42 is angularly arranged on the frame 35 on each side ofthe tape T so that the milling cutter 43 of each skiver engages amarginal portion of the upper surface of the tape T to shave or skivethe tape. In this manner the tape T is continuously tapered along itsopposite longitudinal marginal portions, as represented at 44 and 44 inFigs. 3 and 4, so that the edges will be thinner than the middle portionof the tape and vhence when applied over a wallboard joint the marginalportions 44 and 44 tend to taper into the wallboard. If it is desired toleave the tape T unskived, the skivers 42 are vertically adjusted inorder to raise their milling cutters 43 out of engagement with the tapepassing over the supporting base 4| and the skivers are not electricallydriven.

When the skivers 42 are being operated to taper the edges of the tape Tit is preferred to remove the paper dust which results from the skivingof the tape. To this end, as shown in Fig. 1, a suction manifold 45 isarranged above the tape T and has a duct or tube 46 which extendslongitudinally of the machine to a point in advance of the skivers 42where this tube turns downwardly toward the tape T, the forwardextremity of this tube being formed with a split suction nozzle 41,through which the tape passes so as to remove paper dust from all sidesof the tape. The principal amount of skiving dust is removed by a pairof branch ducts or tubes 48, each of which extends downwardly from thetube 46 toward one of the milling cutters 43 and terminating immediatelyadjacent the respective milling cutters. In this manner, the tape T isleft clean of paper dust after being skived.

The forwardly moving tape T then passes over a crowned roller 49, thencedownwardly and under a guide roller 50, and thence upwardly and over adrive roller 5| fast to a shaft 52 (Fig. 2). Each of these rollers 49,50 and 5| is suitably y mounted on the frame 35 so as to 'be rotatableabout a horizontal axis extending transversely of the machine. Theperiphery of the drive roller 5| is shown as being formed with anoutwardly projecting and circumferentially continuous central ridge 53which impresses a continuous longitudina1 groove 54 (Figs. 3 and 4)centrally in the tape T passing thereover, an adjustable rubber back-uproller 55 pressing the tape` T against the ridged drive roller 5|. Theinterposition of the tape T between the rollers 5| and 55 with theroller 5| being driven serves to unwind or pul1 the tape off the tapesupply roll 39 and'feed theitape at a predetermined...lineari-.apegadaaai? @ages-tors tapei'ILe-i preferably.-providedffwit thegroov. 54 opthat .11. tapefean;.aberreadilyioldedalong a Str ig n Whennised @to -ooverfinside for.outside-corner -on wallsrand n. .the like.

Each jaw 81 is in the form of a flat blade slidably mounted in a radialslot 88 provided in the mandrel head 86 and limited as to radiallyoutward movement by projecting pins 89 and 89 arranged in enlarged holes90 and 90', respectively, provided in the mandrel head. The outer cornerof each jaw 81 is preferably smoothly beveled and the inner edge 9| ofeach jaw is tapered radially inwardly of the mandrel head 86. The innertapered edges 9| of the jaws 81 engage a frustoconical wedge 92reciprocably arranged in a cylindrical recess 93 provided in the mandrelhead 86. This wedge 92 is secured to one end of an operating rod 94which is slidably arranged in a bore 95 provided centrally through theshaft member 85. The operating rod 94 extends completely through thebore 95 so that the free end of this rod can project from the shaftmember 85 as shown in Fig. 12.

As illustrated in Fig. 2, the mandrel 82 at the roll unloading stationcarries a consumer roll R of paper tape tightly wrapped around one ofthe cardboard cores C. In Fig. 12, the condition of the mandrel 82' isillustrated immediately prior to the removal of the roll R therefrom. Inthis condition, the jaws 81 are radially retracted within the mandrelhead 86 so that the outer edges of these jaws do not project beyond theperiphery of the mandrel head, and hence do not clutch the core C.

In order to mount each mandrel on the turret 83, the shaft member 85 isshown in Fig. 12 as being rotatably arranged in the bore of a sleevebearing 96 one end of which is of reduced external diameter, to providea neck 91 projecting through a hole in the turret 83. The outer end ofthe neck 91 is externally threaded to receive a nut 98 which clamps theturret 83 against the shoulder on the sleeve bearing 96 formed by thisneck. A pulley 99 is fast to the outboard end of the mandrel shaftmember 85.

The mandrels 823, 82 and 822 which are illustrated in Fig. 2 at the coreloading, roll starting and roll winding stations, respectively, areshown as being rotated in a clockwise direction about their respectiveaxes whereas the mandrel 82 in the roll unloading station is notrotated. This is accomplished by a fiat belt passing around therespective pulleys 99 for the mandrels 822, 823 and 82 and which alsopasses around a drive pulley |0| fast to the shaft 58 of the gearreducer 51 (Fig. 2). A spring loaded belt tightener |62 -engages thebelt |00 and maintains the same tight at all times.

If the turret 83 were not restrained, it would rotate continuously aboutthe axis of its pivot 84 by reason of the belt |80 driving the mandrelpulleys 99 and particularly if any of these pulleys engaged by the beltresisted rotation. In order to maintain the turret 83 stationary whilethe tape T is wound around the core C on the upper front mandrel 82, aturret stop arm |03 (Figs. 14, 14A, 15 and 16) is oscillatably mountedon the machine frame 35 and has its free end formed to provide asemi-circular socket |04 adapted to engage the bearing sleeve 96 (Fig.14A) of each of the mandrels when in the lower front mandrel position.The hub |05 (Figs. 14 and 15) of the turret stop arm |03 is rotatablymounted on a rod |06 which extends horizontally transversely of themachine and is longitudinally slidably mounted on the left frame plate38 and also in an outboard bearing |01 on the right frame plate The rod|06 is slidable in the hub |0501 the turret stop 'arm los so that thelatter naves in' a 4 tape.

plane spaced a fixed distance from the turret 83. The turret stop arm|03 is actuated by a rock arm |08 connected to the hub |05 and a shipperrod |09 connects this rock arm with a cam lever ||0. A tension springoperatively connects the rock arm |08 with the frame 35 and constantlyurges the turret stop arm |03 to rotate on the rod |06 in a direction toeffect engagement with one of the mandrel bearing sleeves 96. The camlever ||0 extends transversely of the machine and has one end pivoted onthe right side of the frame 35 and its opposite end extends over andengages a cam ||2 mounted on the cam shaft |82 (Fig. 2). The cam I |2 isso formed that upon its rotation it raises the cam lever ||0 therebylifting the shipper rod |09 and swinging the turret stop arm |03 out ofengagement with a mandrel sleeve bearing 96 and permitting the turret 83to rotate in a clockwise direction as viewed in Figs. 1, 2 and 16.

The lineal speed of the belt |00 is such that it tends to rotate thepulleys 99 on the mandrels 822, 823 and 82 so that the peripheral speedof the tape T being 4wound around the upper front mandrel 82 is fasterthan the feed of this Thus the tape T is tensioned to wind a tight rolland the turret 83 will rotate about its pivot 84 when the turret stoparm |03 releases it to do so. However, while the turret stop arm |03 isin its operative position the turret 83 cannot so rotate and the belt|00 rotates the mandrels 822, 823 and 82 about their respective axes. Asthe roll of tape being wound around the upper front mandrel 82 increasesin diameter, the belt |09 slips on the pulley 99 for this mandrel so asto maintain tension in the tape T but insufficient tension to rupturethe tape.

When the core C on the upper front mandrel 82 has a predetermined lengthof tape T wound around it, the turret stop arm |03 is actuated torelease the turret 83 and the mandrel 82 is moved to the lower frontmandrel position or roll unloading station. As the mandrel 82 is solowered the free end of the operating rod 94 of this mandrel engages astationary cam ||3 on the inner side of the left frame plate 38 in themanner illustrated for the mandrel 82 in Figs. 12, 14 and 15. Thestationary cam ||3 is formed with a projecting face engageable with theend of the operating rod 94 to cause the wedge 92 to move out of therecess 93 in the mandrel head 86 and hence permit the mandrel jaws 81which were clutching the core C of the fully wound roll R to moveradially inwardly and thereby drivingly disengage or declutch the roll R(Fig. 12.). It will also be noted that the mandrel in the lower frontmandrel position is not rotated since its pulley 99 is not engaged bythe belt |00.

Means are provided to remove a roll R from a mandrel at the rollunloading station and after such mandrel has been operated to declutchthe core C of such roll. Such means are shown in Figs. 12 and 14-16 ascomprising a. stripper arm H4 having a hub ||5 mounted on the rod |06 toreciprocate with this rod but free to rotate thereon. A semicircularrecess ||8 is provided on one 'side of the free end of the stripper armIM and is adapted to receive a mandrel head 89 (Fig. 16). The stripperarm ||4 is operatively connected with the turret stop arm |03 forrotation therewith by a rod 1 parallel with the operating rod |06. Therod ||1 is secured to the turret stop arm |03 and extends through a holeprovided in thestripper arm H4 whereby 9E# this=.;stripper..arm ,is.slidable .on this; rod..\.-..Norf...

As previously. described,l when .a fully wound. consumer roll R isremoved from the mandrel in the roll unloading station, the cardboardcore C around which thepapertape is wound to vform this roll R is alsoremoved -from .this mandrel.

the broken line position indicated in Fig. 15. This movement withdrawsthe core pusher 44 from the core magazine |39 into the housing |41 andpermits the column of cores C in this magazine to drop by gravity untilthe lowermost core rests against the curved end |43. Thereafter the coreloader |40 moves to the right as viewed in Fig. 15 whereby the lowermostcore C is engaged and pushed by the core pusher |44 onto the mandrel822, the jaws 81 of which are in their radially retracted position so asto permit the mandrel to receive this core. The operative end of thecore pusher |44 is provided with a cut out |50 (Fig. 15) on its frontand rear sides so as to avoid interference with the protruding wedges 92of the two lower mandrels when moved by the turret.83. When the turret83 is rotated the lower rear mandrel with a core C thereon is elevatedtothe upper rear mandrel position and during such ascent the outer endof the wedge 92 of the mandrel engages a stationary cam (Figs. 12 and15) arranged on the interior of the right frame plate 31. Thisstationary cam |5| is formed with a cam face engageable with the outerend of the wedge 92 of each mandrel as such mandrel moves from the lowerrear to the upper rear mandrel positions to move the wedge 92 soengaging the cam face inwardly of the respective mandrel head 92 wherebythe respective mandrel jaws 81 are forced radially outwardly to clutchor non-rotatably hold the core C to this mandrel.. By the time the lowerrear mandrel arrives at the upper rear mandrel position the core C onthis mandrel is firmly clutched thereby so that the core rotates withthe mandrel.

When the tape T being wound up on the upper front mandrel issevered,.the leading end of the severed feed tape is immediately causedto be wound around the core C on the mandrel in the upper rear mandrelposition or roll starting station. The means for accomplishing this willbe described in .association with the mandrel 823 and the core C thereon(Figs. 2, 20, 24 and 25), although it will be understood that the sameoperation is performed on each of the other mandrels V82, 82' and 822when they are brought suc--A cessively into the Vroll starting station.Such meansare shown as including a movable guard |52 normally embracingthe front side of the mandrelA 823 and core C thereon as shown in Figs.2, 2 0 land 24. This movable guard |52 comprises an arcuate body |53having an inner cylindrical guide face |54, as best shown in Fig. 23,arranged in closely spaced relation and concentric with the periphery ofthe core C on the mandrel 323 to provide. a channel into which theleading end of the severed paper tape T can slide between the coreperiphery and the face |54. In order vto yieldingly press the tapeagainst the core the guard |52 carries a spring |55. Referring to Fig.23, this spring |55 is a curved or bowed leaf arranged inra recess |56provided centrally in the inner face |541, one end of this leaf spring|55 being suitably anchored in the recess |56 adjacent one edge ofthearcuate body |53 as indicated at |51. The opposite end or. tail of theleaf spring 55 is free and preferably projects slightly beyond theopposite edge of the arcuate body |53. The leaf spring |55 is formed sothat it tends to seek a curvature having a radius greater than that ofthe face |54 with the result that the intermediate portion of this leafspring projects from the recess |56 and engages the periphery of thecore C as shown in Figs. 20 and 24. The edge of the curved body |53adjacentwhich the leaf spring |55 is anchored at |51 carries a knifeblade |58 which projects generally tangentially from this edge. Thisknife blade |58 is shown as being clamped against a flat surface |59 onthe exterior of the curved body |53 by a clamping block |60 held by oneor more screws |6| screwed into the curved body |53. The knife blade |58is therefore adjustable and removable. The knife blade |58 cooperateswith the movable knife blade 68 to cut the tape T as illustrated in Fig.24.

One end of the guard |52 is formed to provide an arm |62 which issuitably non-rotatably sey cured to one end of a rock shaft |63. Thisrock shaft |63 is suitably journaled on the right frame plate 31 so thatits axis is horizontal and eX- tends transversely of the machine. Theguard |52 is arranged on the interior of the right frame plate 31 (Fig.26).

When the upper knife blade 68 drops and cooperates with the lower knifeblade |58 to sever the tape T, the tape guide press 62 presses theleading end of the severed tape against the top of the core C on themandrel 823 as illustrated in Fig. 24. Inasmuch as the tape T iscontinuing to be fed forwardly by the cooperation of the rollers 5| and55, the leading end of the severed tape is fed into the inlet of thespace or channel between the core C on the inner guide face |54 of theguard |52 and advances between the leaf spring |55 and the core, thisleaf spring yielding to permit this advance of the tape and at the sametime urging the tape against the core. After the leading edge of thesevered tape T has been' so pressed by the leaf spring 55 against thecore C, the guard |52 rotates in a clockwise direction as viewed inFigs. 24 and 25 to the position illustrated in Fig. 25, rotating at aspeed such that the tape is constantly advancing slightly relative tothe guard |52.

In the fully displaced position of the guard |52 as illustrated in Fig.25, it will be noted that the unxed tail of the leaf spring |55 isimmediately under the tape T being guided into the nip between the coreC and the tape extending thereacross. The guard |52 remains in thisfully displaced position on the rear side of the mandrel 823 untilseveral convolutions of the tape T have been wrapped around the core Con the mandrel 823 after which the turret 83 is rotated so as to movethis mandrel with its newly started roll of paper tape forwardly, asillustrated by the broken lines in Fig. 25, to the upper front mandrelposition or rol1 winding station at which the winding is completed. Withthe guard 52 on the rear side of the mandrel 823 (Fig. 25), this mandrelis permitted to be so moved by the turret 83 and after the mandrel |323has left the guard |52 this guard can be rotated back to its originaland normal position (Figs. 2, 20 and 24). rotation back is limited andcontrolled by a stop lug |64 carried by a collar |65 fast to the rockshaft |63, the stop lug |64 engaging one end of a f stop screw |66adjustably held by a bracket |61 secured to the interior of the rightframe plate drive sprocket |68, a chain |69, an idler sprocket |10, areturn spring |1I, a cam lever |12, a cam roller |13 and a cam |14.

egunnnedfvtapegis supported in an geo-sms this rubber roller-is loweredit will press the. leading end |83' into adhesive engagement with v thetrailing end of the severed paper tape T a short distance in advance ofthe transverse severed edge thereof (Fig. 29). This movement of thelever |90 also brings the cam foot |92 into engagement with the movablearm |81 so as to push this arm downwardly thereby to push the clampingbar |85 away from the gummed tape. Therefore, since the leading end |83'of the gummed tape has been stuck to the roll R and the clamping bar |85and rubber roller |85 have been effectively separated to unclamp thegummed tape, this tape is free to move with the roll R' during itsrotation.

The gummed tape is permitted to follow the moving periphery of the rollR until a suitable length of gummed tape has been appliedcircumferentially to the roll R to form a strip S such that the advancehalf of the strip S overlays the trailing end of the tape T and thetrailing half of the strip S overlays an exposed portion of the nextinnermost convolution of paper tape in the roll R'. When such length ofgummed tape has been so applied, the gummed tape is severed. For

this purpose a relatively thin knife blade |94 having a horizontaltransverse cutting edge on its.

lower end adapted to engage the gummed tape is arranged immediatelyforward of the rubber roller |86 for movement in a generally verticaldirection. The knife blade |94 is actuated by a solenoid |95, thearmature of which is suitably connected to this knife blade and urgedupwardly by a tension spring 98 connected to the upper end of anupstanding support bracket |91 suitably secured to the support arm |11(Fig. 2). Energization of the solenoid |95 forces the knife blade 94downwardly from its normally elevated inoperative position intoengagement with the gummed tape thereby cutting it and forming a strip S(Fig. 31). De-energization of the solenoid |95 permits the stretchedreturn spring |96 to lift the knife blade to its normally elevatedinoperative position illustrated in Fig. 28.

The energization of the solenoids |95 and |93 is controlled in a mannerto be described later herein.

While the gummed tape is being applied to the roll R' as illustrated inFigs. 29 and 30, means are provided to unwind a length of gummed tapefrom the spool |83, this slacking operation being necessary sincepositive eiort is usually required to unwind a spool of gummed tape byreason of the convolutions thereof sticking together. Such slackingmeans are shown in varying degrees of particularity in Figs. 1, 2, 5,30, 32 and 33 and include a movable guide roller |98 arranged on thefront and ungummed side of the stretch of gummed tape extending betweenthe spool |83 and rubber roller |86. This guide roller |98 is freelypivoted on the front end of a normally generally horizontally arrangedrock arm E99 (Figs. 1 and 2). The rock arm |99 is arranged on the innerside of the support arm |11 and the rear end of this rock arm is fast tothe pivot pin |19. An actuating arm 200 is arranged on the outer side ofthe auxiliary frame plate |16 and is also fast at one end to the pivotpin |18 (Fig. 5) and when oscillated rocks the rock arm |99. In order toso move the actuating arm 200, the free rear end thereof is connected bya shipper rod 20| to a cam lever 202. This cam lever-202 extendstransversely of the machine and has one of its ends pivotally mounted onthe right side of the machine frame 35 and has its opposite free end 16operatively engaging the periphery of a cam 203 (Figs. 32 and 33). Thecam 203 is mounted on the cam shaft |82 and is formed with a salientpart so that rotation of this cam will swing the cam lever 202 upwardlywhich in turn lifts the shipper rod 20| and which in turn swings theactuating arm 200 upwardly and the rock arm |99 downwardly therebyforcing the guide roller |98 downwardly and rearwardly of the machine(Fig. 30). Such movement of the guide roller |98 at a time when the freeend of the gummed tape is held between the clamping bar |85 and rubberroller |86, pulls a length of gummed tape from the spool |33. Continuedrotation of the cam 293 in the same direction permits the cam lever 202to swing downwardly thereby returning the rock arm |99 and guide roller|98 to their normal inoperative positions. When the guide roller |98 somoves upwardly and forwardly it leaves slack in the unwound stretch ofgummed tape which is taken up when the next strip S is applied to sionis relieved and the mandrel 82 and roll there-V on immediately tend torotate faster. It is desii-able to elininate this tendency to speed upin order to insure that a strip S of gummed ltape is properly positionedacross the severed transverse edge of the trailing end of the tape T andalso to maintain uniformity in the form of complete consumer rolls Rformed on the machine. Accordingly, speed up control means are providedand are illustrated in varying degree of particularity in Figs. l, 2, 5,6 and 28. Such means are shown as including a soft rubber roller 20Garranged on the front of the machine in advance of the upper frontmandrel 82 and suitably journaled in a stationary bracket 205 suitablysecured to the left frame plate 38. The periphery of this soft rubberroller 204 is frictionally engageable with the periphery of the paperroll R when the latter is nearly its full size and shortly before thetape T is severed by the knife blades 98 and |58, the body of thisroller 20d being slightly distorted or flattened at the place ofengagement with the roll R in order to accommodate the increasingdiameter of the roll (Fig. 28). The roller 204 is thus rotated by theroll R'.

Brake or speed control means are operatively associated with the softrubber roller 284 and are operable to maintain the peripheral speed ofthis roller the same as that oi the tape T being wound on the roll Rwhen this tape is severed by the knife blades 88 and |58. Such brakemeans are shown as including a clutch 208 arranged on the left side ofthe machine on the outer end of the.

continuously driven transverse shaft 52 (Figs. 5 and 6). This clutch 20Bincludes a' drive sprocket 201 freely rotatable on the shaft 52 andconnected by an endless chain 208 with a driven sprocket a collar 2 I0secured to the outer extremity of the4 shaft 52- as by apin 2| I andelroller thrust bearing 2|2 vwhich is backedup by acam'collar 2 Iv3. Thiscam collar 213 is rotatably-and Asliiably arranged on the shaft 52andisformedcn itsinner side with a cam face vengaging ya correspondinglyformed-v cam vface onfav stationary .clutch .memf ber 2- I 4suitablyrigidly-connected to the left frame plate 37.2 asfby the bolt2|5. A clutch actuating armv 2|is lconnected with the cam collar 2|3 andextends laterally therefrom as shown in Fig. 5. A shipper rod 2Hconnects the free end ofthe arm 2|5with a pivoted cam lever 2|8 whichextends transversely ofthe machine and rides-on the `peripheryof a cam`2 l2 on the cam shaft |82 (Fig. 5). The camv 2|2 is suitably formed toraise the-cam lever 243-Which vin turn lifts the shipper rodf2|1 andthereby swing the cam actuating armj2 6 upwardly. Upon so swinging thearm 2|6 the cam collar 2|3 is vforced.v to rotate relative tothe clutchmember 2-|4 so that the cam faces of these parts force the cam collar2|3 to slide on the shaft y'iZ'to the left as viewed in Fig. 6.Suchvmovement of the cam collar 2|3, through the thrust bearing 212,shifts the drive sprocket 2t? also to the left and against and intofrictional clutching engagement with the collar 2|@ which is rotatingwith the shaft 52. Therefore the drive sprocket 231 isclutched to theshaft 52 and it will be compelled to rotate at the speed of this shaft.Swinging the clutch actuating arrndownwardly as lpermitted by the cam2|9 operates the clutch parts in lareverse direction and destroys theclutched engagement between the collar 2 IU and drive-sprocket 231.

rWhen-,the roll R- tendsto lspeed up after the tape T-hasbeen cutthereby .-tendingto drive the soft rubber roller 224 faster, thesprocket 222 through the-chain 288 alsorotates the sprocket 23'! faster.However, upon-the cutting of the tape T bytheknife blades =58=and 53,the clutch 236 is actuated `as-described above to control the speed ofrotation of thesoft rubber roller 224 whereby-fthe rollr R' ispreventedfrom speeding up. This controlled rotation of the ,roll R innsures the proper relative timed operation-of the gummed tape applyingmeans and hence the properfapplicationof a strip S of gurnmed tape tothepaper roll.

The driven bevel gear 222 and ratchet wheel 22,9 are freelyrotatable on the `forward end of the cam shaft |82 and are continuouslybeing rotated by the driving mechanism just described.

The one-,revolution clutch referred to is provided between thecontinuouslyy rotating ratchet wheel 229V and the cam shaft |82.Referring to Figs.V 10 and 1l, a disk .230 `is keyed to the cam shaft|32 Vimmediately in front of the cam sleeve 222 and immediately adjacentthe ratchet Wheel 22S and is slightly larger in diameter than .thisratchet wheel. An .ear 23| yprojects outwardly from the periphery `ofthe disk 235i for pivotally mounting a pawl 232 opposite the teeth onthe ratchet wheel 229. The pawl 232 extends downwardly and its ,loweroperative end is constantly urged toward the ratchet wheel 222 by ahelical compression spring 233 arranged in a recess jin the disk 230 andbearing against .an offset arm 234 connected to the pawl. The operativeend ofthe pawl 232 is normally held retracted or `out of engagement withthe teeth on the ratchet wheel 22.8. yForthis purpose the arm 2.34 isprovided with .a generally yhorizontal downwardly facing 4shoulder 235which normallyl rests'on a lug 236 formed on an upstanding shift arm231. The lower endof this shiftarm 2.37 is pivoted on the bedplate 33 ofthe mafzhine-frame,` as indicated at 238 (Figs. 5l and 10), for movementof the shift arm about a horizontal axis `extending transversely of themachine. The upper end of the shift arm 2311s provided with an enlargedhole 240 through which a generally horizontally arranged shift rod 24|extends in a direction longitudinally of the machine frame (Figs. 5 and10). A pair of collars 242 and 243 are arranged in spaced relation onYthe shift rod 24| and adjustably secured thereto by .setlscrews 242'and l243', respectively, the collar242 being arranged on the front sideof the `upper endof the shift rod and the collar 243 being arrangedonvthe rear side thereof :(Fig. 10) t t Referring to Figs. 5 and 10,when the shift rod 24| ismoved'to the left or toward'the front of themachine, the collar 243 pushes the shift arm 231 to swing this arm sothat the lug 23S is pushed out from under the pawl arm 234. Immediatelyupon this freeingor Yunlatchingvof the pawl 232, its operative end ismoved into engagement lwith a tooth on the continuously rotating ratchetWheel 229 by the spring 233. This engagement of the pawl 232 and ratchetwheel 229 drivingly couples the disk 230 with the ratchet Wheel wherebyrotationof the cam shaft |82, kcam shaft sleeve 220 and cams'I'M, ||2,A|34, 203, -BI and-2|9is effected. t

.At the end of one revolution,l the cam .shaft |82 and the Icams thereon.are stopped. TIVo this end, the-rearend of the shift rod 24| issuitably pivotally ,connected to the upper end of a cam operated resetlever 244 which has its lower end Vpivoted on the machine frame 35, asindicated .versely of th machinef A cam roller .2t-Bis car'- ried .bythe lever A2 44 intermediate the 'ends' there- 4of and Ais engageablewith an axiallyfacin'g cam 19 surfae241 formed on the rear side of thecam 8|. When the shift rod 24| is moved forwardly the lever 244 is swungso as to bring its cam roller 246 into engagement with the cam face 241.This cam face 241 is formed with an axially projecting salient part overwhich the roller 246 rides (Fig. 22) so that the lever 244 and the shiftrod 24| will be returned to their original inoperative positions beforethe cam 8| has completed one revolution. During the return or rearwardmovement of the shift rod 24|, the collar 242 thereon (Fig. 10) engagesand pushes the shift arm 231 to swing this arm back to its originalVposition in which the lug 236 thereon will be in the path of theapproaching shoulder 235 of the pawl arm 234 on the disk 236 which isrotating at this time. As the disk 236 completes one revolution theshoulder 235 engages the lug 236 to pivot the pawl 232 against theurging of the spring 233 whereby the operative end of the pawl iswithdrawn from engagement with the ratchet wheel 229. This disengagementof the pawl 232 and ratchet wheel 229 breaks the driving couple to thedisk 239 and this disk, the cam shaft |82 and the cams thereon thus cometo rest after having been rotated one revolution.

In order to prevent over ride, to the extent permitted by the pawl arm234 striking the periphery of the disk 236 or reverse movement of thecam shaft |82 at the end of its one revolution, means are provided toapply a slightly predominant torque to this cam shaft so that theshoulder 235 is urged lightly against and maintained in engagement withthe lug 286. Such means are shown in Figs. 17 and 26 and includes springloaded snubber arms 248 and 249. The snubber arm 248 (Fig. 1'?) ishorizontally arranged with one end pivoted at 256 on the machine frame35 and with its other end carrying a roller engaging the top of the cam|34 on one side of the axis of the cam shaft |82, a tension spring 252connected to the bedplate 36 and arm 248 urging the roller against thecam. This spring loaded snubber arm 248 applies a torque to the camshaft |82 to prevent this shaft from overriding. The snubber arm 249(Fig. 26) inclines upwardly toward the cam |14 in a direction to oneside of the axis of the cam shaft |82 and is suitably pivoted at itslower end at 253 on a bracket 254'secured to the bedplate 36 and carriesa roller 255 on its upper end which engages the periphery of cam |14. Acompression spring 256 is operatively interposed between the arm 249 andbracket 254 and operates to urge the roller 255 against the cam |14.This spring loaded snubber arm 249 applies a torque yto the cam shaft|82 to prevent this shaft from reversing.

Means are provided to intermittently actuate the shift rod 24| to permitthe cam shaft |82 to be driven. Such means are shown in Figs. 5, '1, 8,8A and 9 and include a timing gear reducer 251 driven by the low speedoutput shaft 58 of the main gear reducer 51 and supported on a base 258secured to the bedplate 86 of the machine frame. The output shaft 259 ofthe timing gear reducer 251 rotates very slowly and has a trip arm 260fast to the outboard end thereof. As viewed in Figs. 5, '1, 8 and 8A,the trip arm 269 rotates in a counterclockwise direction. A quicklyvreleasable latch device is arranged adjacent the continuously rotatingtrip arm 268 for actuation thereby. This latch device includes a latchstop 26| supported on an upstanding bracket 262 mounted on the base 258.The rear end 26| of this latch stop 26| is-beveled and vis normallyengaged by a shoulder 263' on a movable latch hook 263 which is pivotedat 264 on the free upper end of an upwardly and forwardly inclined arm265. The center of gravity of the latch hook 263 is in rear of the pivot264. 'Ihe opposite and lower end of the arm 265 is freely rotatablymounted on the outer end of a transverse pivot pin 266 suitablyjournaled on the base 258. The arm 265 is constantly urged to rotateabout the axis of its pivot pin 266 in a counterclockwise direction asviewed in Figs. 5, '1, 8 and 8A by a tension spring 261. The lower endof this spring 261 is suitably connected to the machine frame 35 and theupper end thereof is connected to the outer end of a pin 268 carried bythe arm 265. Referring to Fig. 9, the pin 268 extends completely throughthe arm 265 with an end projecting from each side of the arm and has anintermediate threaded portion 268 screwed in a hole provided in the arm.The outer end of the trip arm 269 is adapted to wipingly engage theforward edge 265 of the arm 265, as illustrated in Fig. 8, to swing thisarm 265 in a clockwise direction against the urging of the spring 261.

A second arm 269 is arranged alongside the arm 285 on the inner side ofand generally par-- allel with the arm 265. The lower end of this innerarm 269 is fast to the pivot pin 266 and its upper end is formed toprovide a radially outwardly projecting finger 269. This nger 269 isadapted to engage a salient part 263" formed on the lower front cornerof the latch hook 263 so that when the finger is forced against thissalient part the rear end of the latch hook swings upwardly. On theother hand, when the finger 269 is out of engagement with the salientpart 263" the latch hook 263 is free to swing downwardly by gravity whenits shoulder 263 is disengaged from the end 26 of the latch stop 26|.

An upwardly and rearwardly inclined arm 210 is fast to the inner end ofthe pivot pin 266 and the outer end of this arm is suitably connected tothe front end of the shift rod 24| (Fig. '1) A tension spring 21| issuitably connected to the arm 210 and to the machine frame 35 (Fig. 5)and constantly urges this arm to swing forwardly. Inasmuch as the arm210, pivot pin 266 and inner arm 269 are a unitary structure, the spring21| acts upon the inner arm 269 to constantly urge the same to rotate ina counterclockwise direction as viewed in Figs. '1, 8 and 8A. Limitedrelative rotative movement between the arms 265 and 269 is permitted bythe inner end of the pin 268 being arranged in a slot 212 provided inthe inner arm 269.

When the outer arm 265 has its latch hook 263 engaging the latch stop26|, the inner arm 269 is forwardly displaced with respect to this outerarm the maximum permitted by the inner end of the pin 268 engaging therear end of the slot 212. The latch hook 263 is held in engagement withthe latch stop 26| by the spring 261. In this condition of the parts, asillustrated in Fig. '1, the finger 269 on the inner arm 269 is forwardlyspaced from the salient part 263" on the latch hook 263 under the urgingof the spring 21 As the trip arm 26|] engages the` outer arm 265 thisarm is swung thereby in a clockwise direction as viewed in Fig. 8 andsuch movement also swings the inner arm 269 by reason of the pin 268being arranged in the rear end of the slot 212. Such movement of theinner arm 269 also swings the arm 210 toward the rear of the machinethereby shifting the shift rod 24| slightly to the rear
